libnv improvements week 5

[Adam Starak]

Hello,

I strongly do apologize for the delay, but I had my last final exam today.
Right now I will fully concentrate on my FreeBSD project. Last week, I
created parser from nvlist to string and cleaned cnv API code. Soom I'll
build kernel and test it. The last step will be to generate patch and
provide it to my mentor/ Can't wait to add a little bit of me to FreeBSD
project.

Best Regards,
Adam Starak
